I've washed them, dried them, sorted them, folded and/or ironed them, placed them in a pile in their rooms. And there they will sit until dd 10 and ds 8 complain they can't find item x or y, and I will drop whatever I am doing to go and look for it, only to have to point out that the missing item of clothing is clean and dry and under their very nose if only they looked, and would be a lot easier to find if they'd put it away. The kids then look at me as if I have horns!
